How it is built
What we do on a permeable tarmac driveway
A permeable tarmac drive uses porous asphalt, a mix with fewer fine particles so water passes through the gaps, laid on an open-graded stone base that stores the rain and lets it soak into the ground.
- Dig out deeper than a standard drive to fit the storage layer
- Open-graded permeable sub-base, often Type 3 or 4/20 stone
- Porous asphalt binder and surface courses
- Overflow to a soakaway or border on slow-draining ground
- Edge restraint that does not block the flow
